From: Marta Lofstedt <marta.lofst...@intel.com>
In OpenGL 4.4, section 4.5, the requirement for interpolation
qualifiers to match over shader stages was removed.
In OpenGL ES 3.1, section 9.2.1 there is a table showing that
centroid does not have to match between shader stages.
Also see bug 92743 for more discussions.
